Embodiment Construction

[0023] For a mutual capacitive touch screen, it includes driving electrodes and sensing electrodes for generating mutual capacitance, and the driving electrodes and sensing electrodes are intersected, and a detection capacitance matrix is ​​formed at the intersections. The extending direction of the driving electrodes is set as the first direction, and the extending direction of the sensing electrodes is set as the second direction. For a single-layer mutual capacitive touch screen, the driving electrodes and sensing electrodes are formed by the same transparent conductive layer.

[0024] The touch screen provided by the present invention is a single-layer mutual-capacitance touch screen, and the touch screen includes first touch electrodes and second touch electrodes distributed along different directions, and the first touch electrodes and the second touch electrodes The electrodes are insulated at the intersecting position, the first touch electrode or the second touch elec...

Abstract

Embodiments of the present disclosure disclose a touch screen and a manufacturing method thereof, and a display device. The touch screen comprises a first touch electrode and a second touch electrode located on a substrate and arranged in cross distribution along different directions. The first touch electrode and the second touch electrode are insulated from each other at a cross position. One of the first touch electrode and the second touch electrode comprises a metal bridging line and a plurality of transparent conductive portions arranged at intervals. The metal bridging line electrically connects adjacent transparent conductive portions arranged at intervals at the cross position. The touch screen further comprises an opaque pattern. The metal bridging line corresponds to a position of the opaque pattern. The opaque pattern can be located at a side of the metal bridging line close to a display image.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to a touch screen, a manufacturing method thereof, and a display device. Background technique [0002] Since the capacitive touch screen has the advantages of high sensitivity, long life and multi-touch support, it has become the mainstream touch technology nowadays. The capacitive touch screen is further divided into a self-inductance touch screen and a mutual induction touch screen, and the mutual induction touch screen is further divided into a single-layer mutual induction touch screen and a double-layer mutual induction touch screen. Among them, the driving electrodes and sensing electrodes of the single-layer mutual-inductance touch screen are formed by the same transparent conductive layer, and the driving electrodes and sensing electrodes of the double-layer mutual-inductive touch screen are formed by two different transparent conductive layers. The manufacturing proc...
